aqa eng lit and lang - 7 - would like a 9 but a 8 is good enough for me in those subjects
ocr b geography - 9

Hi !! Considering you are already at rlly solid grades jumping up to a 9 is more than possible at this stage .I achieved 7 9s and 3 8s last year and my mock grades this time were lower than yours .For sciences and maths you just have to do every single past paper possible (there were sm qs from my year that I have seen come up before ) and for English I was stuck on a 7 for the longest time but for lit watch mr salles although his ideas are sometimes too complex ,including different analysis rlly helps you stand out and if you want to pay money the light up hub does have good analysis although you definitely don’t need it .For language it is all about making the most different interpretations that other students wldnt have picked up on, so just look on mark schemes to see what level 5 responses would have picked up on but obv timing is rlly important and sticking to structures as much as possible . You got this !!!

Thank you so much for the tips... for the section b of the language papers do you have any tips as the most i have got is 28! 😊
